Hi , Brief : 1. Myself and my wife not staying together for last 3 years due to serious issues arised due to involment of FIL and MIL in our life. 2. to mention before we both were staying in rented house from where FIL and MIL along with my wife pushed me out of house saying they will marry their daughter to someone else 3. Now i am staying at my parents place since two years but keeping in mind their behaviour i have also made live and licence agreement with other person . 4. Now few days back FIL started saying they want to compromise but i am not ready for same as during the stay with wife ,she and my MIL had assaulted me .so i have fear of life 5. 2 days back when i was moving out of my parentral home for work these people along with some 10 to 15 other people suddenly came in front and said they want to talk and lets go in parental home and talk. 6. I could very well make out that they were trying to get entry in house but i some how i stopped them and discussed outside house and send them back. 7. later my mother filed NC under 506ipc 8.now i would like to know what further games these people can play and what precautions i should take. please not that my parents will be soon going out of country for next 15 days ,
